But while his men were asleep his enemy came and sowed weeds among the wheat, and went away. When the crop came up and ripened, the weeds appeared as well. Then the owner’s servants came up to him and said, ‘Sir, didn’t you sow good seed in your field? Where did all these weeds come from? ‘Some blackguard has done this to spite me.’ he replied. ‘Do you want us then to go out and pull them all up?’ said the servants. ‘No,’ he returned, ‘if you pull up the weeds now, you would pull up the wheat with them. Let them both grow together till the harvest. And at harvest-time I shall tell the reapers, ‘Collect all the weeds first and tie them up in bundles ready to burn, but collect the wheat and store it in my barn.’”
